I let my board (#171) run through the evening. The accepted shares reported in MPBM is roughly equal to my Icarus board that is installed on the same system which tells me that I'm still only hashing at 380mh/s.

The only difference I have is SW6 #1 is on, if it is off then it won't hash. This all using the SPI flash.

With SW6 #1 on you run them on the half Mhz as with SW6 #1 off.

My SN# 0015 board is not working with the 160Mh bitstream. If I have time I will test it with the 140 and 150Mh bitstreams.

I have the 150 Mhz version running on my S/N 26 board. Or are you talking about the 160+ Mhz bitstreams? Didn't try them, yet...

Boards 0-50 have SERIOUS issues, later boards just issues Sad

"Serious" as in "cannot be fixed in software"? I'm rather concerned because I have "pre-50" board.

Yohan, can you comment on this?

I don't know how much serious problems they have or whether they can be fixed in software, but the fact that makomk bitstream doesn't work on them while it works on ebereon's ones (which has boards with serial number >= 400) without issues makes me think that it is serious enough.

Makomks 160mhs bitstream ran on my 3 boards for 9,5h before failing, a board had dissapeared from device manager.

I would say, thats a USB cable problem. As I had the same issue with 4 boards and since I changed them, everything is ok.

Yeah, a bad bitstream shouldn't be able to cause that - USB's handled by a different chip, which presumably runs off seperate power rails to the FPGA and a seperate clock source. Though you never know with the Cairnsmore1.

Yes I had 4 broken USB cables...

Yes, the FTDI Chip have a serial number. I see it when I start the Enterpoint VM and under the USB devices when i hold the mouse over a board it shows my something like FXZGXXX.

Thanks, now I need a way to be able to read it on linux, since lsusb tells me nothing.

spiccioli

Not true, it needs to be called as root to see serial number

Code:

sudo lsusb -v | grep iSerial
  iSerial                 1 0000:00:10.4
  iSerial                 1 0000:00:10.0
  iSerial                 1 0000:00:10.1
  iSerial                 1 0000:00:10.2
  iSerial                 0 
  iSerial                 0 
  iSerial                 3 FTVJ5AGN
  iSerial                 3 FTVJ5A9N
  iSerial                 3 FTVJ5AFK
  iSerial                 3 FTVJ5AB9
  iSerial                 3 FTVJ59WC
  iSerial                 3 FTVIDJ4R
  iSerial                 3 FTVJ88QX
  iSerial                 0 
  iSerial                 3 FTVIUONW
  iSerial                 3 FTVJ5ALH
  iSerial                 3 FTVJ88VS

here they are, FTV....

Hi,

I have a question: do the boards have a serial number? I mean, not the one written on the outside, but one that can be used to write an udev rule so that the same board ends up on the same ttyUSBnn no matter what cable/usb hub port I'm using.

spiccioli.

ps. I'm giving up on bitstreams Sad

, either boards below serial 400 have issues or the 160 bitstream does have problems. I can't mine for more than a few hours, sometimes even ony few minutes, before cgminer tells me they failed. with twin_test.bit I could mine for weeks without problems, slowly, but without problems.

I think atleast boards 0-50 have issues. Not sure about 50-400.

I have 9 boards past serial number 100.

BTW, Glasswalker tells us that the serial code inside the icarus bitstream is not optimal for cairnsmore hardware, but I fear that this is not the whole story since latest report from Yohan says that they still cannot mine on FPGA3.

On the other end makomk's bitstreams mine without problems on FPGA3, with latest boards at least.

So I'm starting to think that boards past number 400 (or maybe a lower number) are OK, while previous boards have various degrees of hardware problems which make it more or less impossibile to use all four FPGAs (or use them reliably).

I'd like to have a definitive answer on this by Yohan so that I can stop spending my time trying to make my boards work.

what are your temps and power usage?

Ambienttemperature directly on the rig is 32°C, Roomtemp is ~22°C.

10 Boards:
37 fpga's with 190Mh bitstream
3 fpga's with 160Mh bitstream (only fpga1, fpga0 have 190Mh on these problematic pairs)
1x 10 Port USB hub
1000W old ATX PSU

150 Mhz bitstream working on my sn 26 board for 5+ hours. I won't bother trying the 160 mhz version, but I will now flash the SPI and let it run for some days.

Here is a screenshot of mpbm after 5 hours:

On 3 boards fpga1 is not working propably, on SN# 414 it hang's/frozen. LED's still ok on these 3, but fpga1 is not providing shares like the others. I will flash these with lower bitstreams and report back how it works.

Well, the shortfin_icarus_cm1_test_160.bit on four of my boards (serial n. 104, 130,134,137) worked on two of them for just a few hours.

Wait, does that mean your board serial number is 8? If so, don't bother - apparently my bitstreams don't work on boards 1-50.

I flashed the shortfin_icarus_cm1_test_160 on my 0005 board, and it seems to be working without problem for at least the last 7,5 hours:
